Same here. It is the hardware and Windows compatibility that got me into the Mac camp. I do not have much interest in radically different hardware, ARM or iOS. If the mini became a one-piece, glued together Internet appliance I doubt if I would have one.
But what happens when ARMs have the power of x86 processors and are a lot cheaper.
What do you do with those chips?
Sooner or later they are going to migrate to laptops just because of battery life and efficiency.
AnandTech claims that the only bottleneck for the A7 from being a desktop computer chip is the RAM.
Apple has solved that problem with partnering for DDR4 manufacturing.
More ARM design work is moving inside Apple.
Something has to come of the chips other than run a phone or tablet.
I'm not advocating the Mini ARM but I think the future will be these chips for mobile computing and even though the Mini is not really mobile it follows that platform.
